Photoshop Levels adjustment question

If you click on the "Levels" adjustment box, is there any way to make the adjustment screen larger than the little small window in the panel? I usually just make a new layer and hit "Ctrl-L" for the full adjustment window, but I was just wondering if there's another way as there most usually is with photoshop

Which version of PS?

I'm currently running CS6

Not that I know of and the difference in the window is not that much. The biggest drawback would be that the ctrl+L method doesn't allow you go go back and make changes where using Levels Adjustment layer does.

Indeed......I just like the bigger window for fine tuning it. Works better for me for whatever reason, but I was hoping the adjustment layer could be blown up to have the best of both worlds

remembered seeing it one day browsing through all that stuff.
